Quasielastic axial-vector mass from experiments on neutrino-nucleus scattering

We analyse available experimental data on the total and differential charged-current cross sections for quasielastic nu N-mu and (nu) over bar N-mu scattering, obtained with a variety of nuclear targets in the accelerator experiments at ANL, BNL, FNAL, CERN, and IHEP, dating from the end of sixties to the present day. The data are used to adjust the poorly known value of the axial-vector mass of the nucleon.
